Piezoelectric catalysis is an emerging research field in recent years. Since the catalytic reaction usually occurs on the surface, the specific surface area is very important for piezoelectric catalysis. Therefore, nanoparticles and nanowires have been developed for piezoelectric catalysis and have attracted widespread attention. However, in actual water applications, the use of nanoparticles will cause secondary pollution. Therefore, an overall deformable nanoporous system is urgently needed to adapt to the shapes of various ultrasonic transducer heads. We have obtained macroscopically inorganic flexible barium titanate nanofiber membranes through electrospinning technology. Without traditional organic mixtures, the surface of the piezoelectric material can fully come into contact with water. The fiber membrane is macroscopically integrated, deformable, and can fully adapt to multiple ultrasonic transducers of various shapes. Calcium doping can effectively improve the catalytic effect, and the catalytic rate (k × 103) of the material with the highest doping concentration can reach 24.47 min−1. In addition, studies have found that lowering the calcination temperature can effectively improve the flexibility of the fiber membrane, which can be attributed to smaller barium titanate grains formed at low temperature. This work provides a generic method for preparing flexible inorganic piezoelectric materials that can be adapted to a variety of surfaces, and successfully applies it in the field of piezoelectric catalysis, which provides an important way for the practical research of piezoelectric catalysis in the future.

The light-soaking (LS) effect has been reported to limit the accuracy and stability of device power output of perovskite solar cells (PSCs) and it is significant to develop effective approaches and strategies to eliminate the LS effect in PSCs. There are very few reports on suppressing the LS effect in CsPbI 2 Br-based all-inorganic PSCs. Herein, a method to eliminate the LS effect by synchronous passivation of anionic and cationic defects in CsPbI 2 Br perovskite film is demonstrated. The 4-(chlorosulfonyl)benzoic acid (CSBA) is added into perovskite precursor and the in situ generation of I 3 − effectively passivates the anionic halogen vacancy defects in CsPbI 2 Br. In the meantime, the Lewis base groups on CSBA coordinate with Cs + and Pb 2+ to passivate the cationic defects. This zwitterionic passivation effect of CSBA remarkably cuts off the path of defect-induced charge recombination and thus eliminates the LS effect. This work offers a deep opinion for future researchers to modulate the LS effect of all-inorganic PSCs.

Innovative solid-phase adsorbent is needed urgently for highly efficient extraction of mercury (Hg(II)) from aqueous solution. Herein, highly porous inorganic materials , including ZrOx, ZrOxyPhos and ZrSulf, were obtained from topotactic transformations of metal–organic frameworks (MOFs) via a facile ligand extraction process, which preserved the original MOF morphology and introduced useful functionalities. ZrOx and ZrOxyPhos exhibited high adsorption efficiency for Hg(II). And ZrSulf showed fastest adsorption kinetics (1.1 × 10 −2 g/(mg min)) and highest adsorption capacity (824 mg/g) among the obtained three inorganic materials due to the presence of accessible sulfur-based functionality, which surpassed most of other benchmark porous adsorbents. Moreover, ZrSulf showed good regeneration ability and excellent selectivity for Hg(II) in the presence of other coexisting metal ions , such as Cd(II), Ni(II), Co(II), Mn(II) and Zn(II), and other inorganic cations , such as K + and Na + . The excellent adsorption performance of ZrSulf towards Hg(II) can be traceable to the covalent bond formation with sulfur-based functionality combined with ion exchange with Na. Given its low-cost and easy preparation nature, ZrSulf could be potentially valuable candidates for the elimination of Hg(II) from aqueous media. Changing the MOF templates and using different digest solutions will introduce different metal and structural possibilities, which demonstrates the potential of such ligand extraction method for synthesizing porous inorganic adsorbents for heavy metal ion decontamination .

Halide perovskite nanocrystal (PNC) of 3D CsPbX3 as a scintillator has aroused intensive attention with advanced applications in radiation detection and X-ray imaging. However, the low light yield and serious toxicity of Pb2+ severely hinder advanced optoelectronic applications. To reduce these fatal shortcomings, a family of new environmentally friendly 0D hybrid lead-free indium halides of [DADPA]InX6·H2O (DADPA = 3,3′-diaminodipropylamine; X = Cl and Br) was prepared. Upon UV excitation, these halides display strong broadband yellow-orange light emissions, and the photoluminescence quantum yield (PLQY) can be optimized up to near unity through the Sb3+-doping strategy. Significantly, high PLQY, negligible self-absorption and low attenuation ability toward X-ray render extraordinary scintillation performance with a high light yield of 51 875 photons MeV−1 and ultralow detection limit of 98.3 nGyair s−1, which is far superior to typical 3D PNC scintillators. Additionally, the ultra-high spatial resolution of 25.15 lp mm−1, negligible afterglow time (2.75 ms) and robust radiant stability demonstrates excellent X-ray imaging performance. To the best of our knowledge, this is the first report on X-ray scintillation based on 0D indium halide materials.

Designing organic fluorescent and phosphorescent materials based on various core fluorophore has gained great attention, but it is unclear whether similar luminescent units exist for inorganic materials. Inspired by the BX 6 octahedral structure of luminescent metal halide perovskites (MHP), here we propose that the BX 6 octahedron may be a core structure for luminescent inorganic materials. In this regard, excitation-dependent color-tunable phosphorescence is discovered from α-AlF 3 featuring AlF 6 octahedron. Through further exploration of the BX 6 unit by altering the dimension and changing the center metal (B) and ligand (X), luminescence from KAlF 4 , (NH 4 ) 3 AlF 6 , AlCl 3 , Al(OH) 3 , Ga 2 O 3 , InCl 3 , and CdCl 2 are also discovered. The phosphorescence of α-AlF 3 can be ascribed to clusterization-triggered emission, i.e., weak through space interaction of the n electrons of F atoms bring close proximity in the AlF 6 octahedra (inter/intra). These discoveries will deepen the understanding and contribute to further development of BX 6 octahedron-based luminescent materials.

A new electrochemical sensor based on a novel organic–inorganic material (PNFCTs) was proposed for detection of paracetamol in this paper. First, PNFCTs were prepared with multi-walled carbon nanotubes (MWNTs) and a derivative of 3,4,9,10-perylenetetracarboxylic dianhydride (PTC-NH 2 ) via cross-linking method. Then, PNFCTs were coated onto the surface of the glassy carbon electrode (GCE) to form porous organic conducting polymer films (PNFCTs/GCE), which could not only increase the loading of paracetamol efficiently but also provide an interface with exceptional electrical conductivity for paracetamol. Finally, gold nanoparticles (GNPs) were attached to the electrode surface through electrodepositing method, which obtained GNPs/PNFCTs/GCE electrode. The electrochemical behavior of paracetamol on GNPs/PNFCTs/GCE was explored by cyclic voltammetrys (CVs) and differential pulse voltammograms (DPVs). The results showed that the GNPs/PNFCTs/GCE exhibited excellent electrocatalytic activity to paracetamol, which should be attributed to remarkable properties of the new composite nanomaterials with porous nanostructure and exceptional electrical conductivity. The wide liner range and detection limit were 0.3–575 and 0.1 μM, respectively. Finally, it was successfully used to detect paracetamol in dilution human serum and commercial tablets. The sensor shows great promise for simple, sensitive, and selective detection paracetamol and provides a promising approach in paracetamol clinical research and overdose diagnostic applications.

In this work, we synthesized CuInSe 2 quantum dots (CISe QDs) and applied them to perovskite solar cells (PSCs) as an inorganic hole-transporting material (HTM). A power conversion efficiency (PCE) of 12.8% was achieved for the PSCs using CISe QDs as the HTM, which is the highest value reported to date for devices with a Cu-based chalcopyrite semiconductor as HTM. More importantly, the stability of PSCs with CISe QDs was significantly improved compared with that of the devices using spiro-OMeTAD as the HTM. These results demonstrate that CISe QDs are a promising inorganic HTM for PSCs with long-term stability and low cost.

Piezoelectric catalysis has become an emerging research field in recent years, which has received extensive attention. Nanoparticles and nanowires have been developed as piezoelectric catalytic materials. However, in practical research, the use of nanoparticles is not easy for the recovery of samples and will cause secondary pollution, and the current piezoelectric catalysis requires the help of high-frequency ultrasound, which increases the consumption of extra energy and cannot be applied on a large scale. In this study, a self-supporting macroscopic flexible inorganic (Ba,Ca)TiO3:Pr nanofiber membrane was successfully prepared by electrospinning. Natural energy (water flushing) was used to drive the flexible inorganic (Ba,Ca)TiO3:Pr nanofiber membrane for piezoelectric catalytic degradation of organic dyes. The results show that the flexible inorganic (Ba,Ca)TiO3:Pr nanofiber membrane driven by water washing has an obvious piezoelectric catalytic degradation effect on dyes. When the water flow rate was 450 L/h and the concentration of CR solution was 10 mg/L, the catalytic efficiency can reach 91.69%. This study provides a green and feasible method for the preparation of flexible inorganic piezoelectric catalytic materials and the catalytic degradation of organic dyes.

Organic-free perovskite solar cells (PSCs) have been considered as the most promising candidate for achieving long-term stability. Here, we demonstrate an organic-free PSC consisting of inorganic CsPbI2Br perovskite, nickel oxide hole transport layer, and niobium oxide electron transport layer. A maximum power conversion efficiency (PCE) of 11.20% is achieved with an active area of 5 cm2, and it increases to 14.11% with smaller area. More importantly, the organic-free PSCs show excellent thermal stability with PCE remaining above 98% of its initial value when heated at 100 °C for 150 min. Postannealing at a proper temperature further increases its maximum PCE to 14.45%, which is the highest among any reported all-inorganic PSCs with a p-i-n structure. The enhanced performance of the postannealed device is ascribed to the decreased trap-state density and improved interface charge-transfer properties. These results demonstrated that this novel organic-free device architecture can be employed to fabricate efficient and stable PSCs for large-scale manufacturing.

Exploration of new compounds belonging to unusual families is always attractive for the everlasting development of material science. Here, three isomorphic rare-earth sulfide borates RE 3 S 3 BO 3 (RE = Nd, Tb, Dy) have been obtained via a facile metal oxide-boron-sulfur solid-state routine. Their centrosymmetric triclinic structures feature 3 D framework built by three types of REO x S y units, viz. REOS 6 , REO 4 S 3 , and REO 3 S 6 . Their structural relationship with similar phases and lanthanide contraction rule are discussed. Their optical band gaps are measured to be 2.59–2.70 eV, and the corresponding theoretical calculations are also performed. This work enriches the rarely studied chalcogenide borate system and is conducive to discovering more inorganic materials .

We developed paper-based powder X-ray diffraction (PP-XRD) to implement phase identification and/or crystal structure determination on paper-based platforms. These aims are not possible with other paper-based detectors, such as Raman spectroscopy and mass spectrometry. PP-XRD overcomes these limitations. Here we reported the simple and low-cost in situ PP-XRD protocol for phase identifications of inorganic and organic materials. We demonstrated that sample amounts of lead nitrate on paper substrate can be reduced into 1/30 of conventional ones by using the standard glass substrate at the same signal-to-noise ratio (S/N) of the X-ray diffraction (XRD) pattern. The paper-based method was comparable in sample quantity and intensity with zero background holder method, even though single crystal Si(100) substrate as zero background holder was used for the specimen preparation of CTAB (C 19 H 42 BrN). More importantly, paper substrates helped reduce preferred orientation that was generally present in routine powder XRD. Also, combined with paper chromatography , overlap peaks were eliminated in the XRD detection patterns of lead nitrate and cobalt nitrate hexahydrate. This new PP-XRD protocol may accelerate the process to identify phase or determine the molecular structures of new materials using trace sample directly. It also includes a hyphenated technique of powder XRD with a simple paper-based microfluidic separation of chemical solutions .

Thermal safety remains a critical factor for the widespread adoption of sodium-ion batteries as next-generation energy storage technology. Conventional organic interfaces with poor thermal stability fail to protect the sodiated hard carbon formed through multimodal sodium storage under various abuses, particularly the highly reactive sodium clusters formed by pore filling, thus introducing substantial potential safety risks. Herein, a dual-functional high-entropy solid electrolyte interphase featuring a disordered hybrid of inorganic components is constructed on hard carbon. The high-entropy inorganic interface contains multidimensional ion transport channels with low diffusion energy barriers to drive sodium-ion deep storage with more pore-filling pathways in hard carbon, largely increasing the sodium storage capacity. NaNi1/3Fe1/3Mn1/3O2/hard carbon coin cell demonstrates 80% capacity retention after 800 cycles at a cathode loading of 17 mg cm–2. The energy density of 146.2 Wh kg–1 is achieved for the 3.7 Ah 26700 cylindrical cell. Concurrently, the thermally stable inorganic-rich interface strongly hinders the heat production from electrode–electrolyte reactions, significantly enhancing thermal safety of sodium-ion batteries. The thermal runaway onset temperature of the fully charged pouch cell is increased from 52.4 to 161.9 °C, and the maximum temperature rise rate is decreased from 1628.5 °C min–1 to 17.4 °C min–1. This work provides new insights into modulating the sodium storage mechanism and enhancing the safety of sodium-ion batteries.
